无线接入系统干扰规避检测方法研究

Research on interference avoidance detection method for wireless access system

介绍了无线接入系统为实现频谱的兼容共享所采取的干扰规避机制的类型,并对具体的检测方法,如信道占用时间评估、空闲信道评估、空闲信道评估时间累积概率分布统计、干扰信号检测阈值的判定、静默期时长以及等效占用率等,进行了阐述。重点指出了在实际的设备检测系统中存在的问题,并给出了更加有效的信道占用时间和空闲信道评估算法以及判定流程。

The types of interference avoidance mechanisms adopted by wireless access systems to realize spectrum sharing and compatibility were introduced,and the specific detection methods such as channel occupancy time,idle channel evaluation,idle channel evaluation time cumulative probability distribution statistics,determination of inter-ference signal detection threshold,silent period duration and equivalent utility were explained.The problems in the actual device detection system were highlighted,and new effective channel occupancy time and idle channel evalua-tion algorithms and the determination process were given.
